First Aid Measures

Ingestion

If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.

Inhalation

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.

Skin

Get medical aid. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse.

Eyes

Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.

Handling and Storage

Storage

Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

Handling

Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Do not breathe dust, vapor, mist, or gas. Do not ingest or inhale.

Hazards Identification

Inhalation

Effects may be delayed. May cause cyanosis, characterized by bluish-colored skin. May cause effects similar to those described for ingestion. Causes irritation of the mucous membrane and upper respiratory tract.

Skin

Causes skin irritation. May be absorbed through the skin.

Eyes

Causes moderate eye irritation.

Ingestion

Harmful if swallowed. May cause irritation of the digestive tract. Effects may be delayed 2 to 4 hours. May form methemoglobin which in sufficient concentration causes cyanosis.

Exposure Controls/Personal Protection

Personal Protection

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.

Respirators

A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.

Exposure Effects

Chronic inhalation and ingestion may cause effects similar to those of acute inhalation and ingestion.

Fire Fighting Measures

Fire Fighting

Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use extinguishing media most appropriate for the surrounding fire. In case of fire use water spray, dry chemical, carbon dioxide, or chemical foam.

Fire Potential

Non-Combustible

Accidental Release Measures

Small spills/leaks

Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation.

Stability and Reactivity

Incompatibilities

Acids, acid chlorides, acid anhydrides, chloroformates, strong oxidizing agents.

Stability

Stable under normal temperatures and pressures.

Decomposition

Carbon monoxide, oxides of nitrogen, irritating and toxic fumes and gases, carbon dioxide, cyanides.

Combustion Products

Fire may produce irritating, corrosive and/or toxic gases.
